Start from the problem.
Every site situation has a system, not a single product: the technical reasoning, the construction details and the materials it is built from.
White tank
The structure itself is the waterproofing. No membrane to lay, no sheet to protect: watertightness is decided at the batching plant and at the joints.
See the systemRetaining wall in groundwater
When the below-grade structure sits in groundwater, hydrostatic pressure is permanent and finds every flaw. The choice changes radically depending on whether the excavation is still open or not.
See the systemLeaking basement
The structure is built, the backfill is in, and water gets in. The work is done from the inside, in three stages that must be followed in order.
See the systemReinforced concrete repair
Spalling cover concrete is not a cosmetic issue: it is the visible symptom of a process eating away the reinforcement. Repairing means stopping that process, not covering it.
See the systemRising damp in masonry
Water rises from the ground through the capillaries of the masonry and stops where it evaporates, leaving the salts behind. A chemical barrier interrupts the path without touching the structure.
See the systemConstruction joints and joints
A construction joint is the interface between two pours placed at different times. It is not a defect: it is a design choice that must be engineered as such.
See the systemSwimming pools
A swimming pool is a tank that works the other way round: water pushes from the inside, permanently, and is chemically aggressive. No other structure puts waterproofing under such continuous strain.
See the systemRoofs and terraces
Demolishing a terrace's paving costs more than the waterproofing itself. Fast liquid systems let you work straight over the existing floor.
See the systemDrinking water reservoirs
In drinking-water structures, waterproofing must not just hold: it must be certified for contact with water intended for human consumption.
See the systemSewage treatment and process tanks
In treatment plants, concrete suffers three attacks at once: chemical, biological and mechanical. It is the harshest environment a structure can work in.
See the systemFacades and exposed concrete
On architectural concrete, quality is decided before the pour, with the release agent, and preserved afterwards, with hydrophobing.
See the systemTunnels and underground structures
In major underground works, waterproofing is no longer repairable once in service. Every choice must be made knowing it will be final.
